I LIGHTING FIXTURE Filed May 12; 1927 I rn/en for Patented Dec. 3, 1929 PATENT OFFICE JOHN F. WENZ, OF WIREIQN, PENNSYLVAIJIA LIGHTING FIXTURE Application filed May 12,

This invention relates to lighting fixtures and more particularly to globes for use with electric bulbs.

It has heretofore been the general-practice to provide a separate means for supporting the globe, such means generally comprises chains, cords or a bell shaped member attached to the ceiling and adapted to support the globe. This construction is undesirable,

due to the expense involved in its manufacture, awkwardness in installation and the irregular manner in which the light is distributed. I have found in practice, that in order to get an even distribution of light in a room, particularly where it is desired to employ only one electric bulb, to position the light a predetermined distance from the ceiling of such room, so that the light from the electric bulb will have a greater range with respect to the ceiling, as well as the other portions of the room. l Vhen an electric light bulb is disposed close to the ceiling, a

small bright ring is reflected around such light bulb, whereas if this light is suspended a predetermined distance from the ceiling, the reflection of the light produces a wider ring of light about the ceiling and causes a more even distribution of the light throughout the entire room. I have found that in providing a suspended light with a translucent glass globe or a globe of any suitable translucent material that the light is still more evenly distributed.

An object of this invention is to provide a globe for use with a suspended electric bulb, that shall be simple in construction, which will present a very neat and highly attractive appearance in use and which will bring about a proper and pleasing distribution of the light from the electric bulb.

Another object of this invention is to pro vide a unitary globe for use wit-h a suspend ed bulb, the said globe having a bowl portion and a relatively long reduced or neck por tion.

Another object of this invention is to provide a unitary globe having the above characteristics that shall utilize the light gen erated by a source of light in a very economical manner.

1927. Serial No. 190,824.

Other objects lie in the novel construction and desirable characteristics that will be made apparent throughout the further description of the globe illustrated in the accompanying drawing and set forth in the ap pended claim.

The single figure is an elevational view of a suspended electric bulb provided with a globe embodying the invention, the globe being shown in section. so

This invention comprises in general, a globe 11 positioned about the suspended electric bulb 12. The electric bulb 12 is suspended by any suitable means such as shown at 13 and the globe is fastened to the ceiling by any suitable means such as shown at 14.

The globe 11 comprises a reduced upper port-ion or neck 15, a hemispherical or intermediate portion 16 and a bottom spherical portion 17 The entire globe is composed of To the same material and is a unitary member. This is a very important feature of the i11- vention as the cost of manufacturing such a globe is considerably less than the cost of manufacturing globes and the separate sus T5 pension means for supporting them. The neck portion, as well as the other portions of the present globe, serves to distribute the light from the electric bulb.

The upper and lower spherical portions 16 g and 17 of the globe 11 are joined together at the circumference of circular sections lying in a plane common to both portions 16 and 17 as indicated at 18. The cylindrical or neck portion 15, as shown, is symmetrical with respect to an axis normal to the plane containing the circular sections at the center of said sections.

The present globe is preferably made from translucent glass and the hemispherical or bowl portion 16 reflects the light rays to the bottom or convexed portion 17. This convexed portion 17 is also subjected to the direct rays of light from the electric bulb and serves to spread such light to illuminate the greatest a possible area.

The present globe 11 may be varied in size for use with different installations and the neck portion 15 is always provided with a diameter slightly greater than the greatest r"- diameter of the electric bulb with which it is to be employed.

\Vhile I have illustrated and described this invention in connection with a single light, it will be apparent to those skilled in the art that certain changes, modifications, substitutions, additions and omissions may be made in the invention without departing from the spirit andscope of the appended claim.

What I claim as new and desire to secure by Letters Patent is:

A light globe comprising bottom and top 7 spherical portions integrally joined together at the circumference oi" circular sections of equal diameters lying in a plane common to botli'portions, the diameter of the sphere including said bottom portion being materially larger than the diameter of the sphere includingrthe upper portion, and a cylindrical portion integrally secured to said top spherical portion, the cylindrical portion being symmetrical with respect to an axis normal to said common plane at the center of said circular sections. Y

In testimony whereof, Ihave hereunto subscri ped my name this 17th day of December, 192
